TC4(Ti-6Al-4V)合金是国内应用最广,产量最大的钛合金。是一种α+β型合金,其熔点在1570℃~1650℃之间,α+β相到β相的转变温度为980±10℃。实验用TC4合金取自西北有色金属研究院工业化生产并经退火处理的10mm棒材。退火后的金相组织为典型的等轴α+β相。退火棒材加工成8mm
TC4 (Ti-6Al-4V) alloy is the most widely used, the largest output of titanium. Is an α + β type alloy having a melting point of 1570 ° C to 1650 ° C and a transition temperature of α + β phase to β phase of 980 ± 10 ° C. Experimental TC4 alloy obtained from the Northwest Nonferrous Metal Research Institute of industrial production and annealed 10mm bar. The microstructure after annealing is a typical equiaxed α + β phase. Annealed bar processed into 8mm
